CUTTER-BAR.

SFECIFIGATION forming part of Letters Patent No. 402,159, dated April`30, 1889:

i Application filed November 10,1887. Serial No. 254,778. (No model.) vv To all whom t may concern:

Be it known that I, CALEB HANK, a citizen of the United States, residingat Jackson, in the county `of Jackson and State of Ohio, have inventedcertain`new and useful Improvements in Cutting Apparatus; and I dohereby declare the followin gto be a full, clear,

and exact description of the invention, such as will enable othersskilled in the art to which it vappertains to make and use the same.

My invention relates to an improvement in cutting apparatus.

Hitherto cutterbars have been provided With a removable sectionextending over the knives to secure them in place; but the constructionhas been such `as to require a special cutter or a special constructionof the bar itself, the present state of the art in the line of myinvention disclosing a cutter-bar provided With studs projectingupwardlyfrom a rabbeted portion of the cutter-bar adapted to extendthrough holes formed in the middle portions of the cutters-one ineach-the cutters to abut against a shoulder on the cutterbar, t-he topsof the studs being iiush with the upper faces of the cutters, and aremovable bar to be secured over the rear upper faces of the cutters tolock them in position; or the cutter-bar has been provided withdowel-studs set in its upper face--two for each cutter--and cuttersprovided with sockets in their lower faces to receive and correspond tothe shape of the upper ends of the doWelstuds have been provided, thecutters being locked in position by a removable bar.

The object of my present invention is to provide a-cutter-bar of suchconstruction that the cutters-one or more of themmay be removed andreplaced at pleasure Without disturbing the cutter-bar itself andWithout cutting rivet-heads, and to further provide a cutter-bar whichmay be readily attached to the mowers and reapers now in use and adaptedto the cutters commonly in use, and still further to provide alocking-bar in connection `with my improved cutter-bar which may beemployed in connection with the cutterbar and cutters of machines now incommon use.

Vi'th these ends in vien7 my invention consists in certain features ofconstruction and ,combinations of parts, as will be hereinafterdescribed, and pointed out in the claim.

In the accompanying drawings, Figure l is l with the bar, when a new baris supplied, or

maybe iirmly set in the holes of the old bar When that is utilized. Thestuds a-two for each cutter-correspond to the two holes in the cuttersin common use and project up- Wardly above the upper face of the bar A adistance equal to the combined thickness of the cutter and the lock-bar.

B represents one of the cutters, of usual construction, provided Withits two holes b to receive the fasteningstuds. In the present instancethe cutter is intended to slip over two adjacent studs with a snug fit,but capable of being readily removed therefrom.

C represents the locking-bar. It consists of a plain fiat bar of metalbeveled on its front upper corner and provided With a series of holes,c, corresponding to the studs a in the cutter-bar, and is adapted to beslid downwardly over the tops of the studs into contact With the upperfaces of the cutters When the latter are adjusted in position for use.The bar C is further provided With three holes, D, (more or less,) toreceive fastening-screws d, to secure the bar C to the cutter-bar, andthereby lock the cutters in position. Since the bar C is capable ofbeing pressed into contact with the upper faces of the cutters,vthere isno opportunity for the cutters to Work up and down or tilt on theirstuds-an objection to the construction referred to above, Where studsproject through the cutters and rest in contact Wit-h the un der face ofthe bar; and, furthermore, as the studs are supported at both ends, theyare prevented from bending and are less likely to become broken by anunusual strain on the cutter. l

IOO

The eye E, through which the cutter-bar is coupled to theconnecting-rod, may be formed integral with the locking-bar or may beformed independently, as shown, and secured to the cutter-bar.

This cutting apparatus may be attached or applied to all reapersandmowers now in use by simply raising the buttons or keepers (three ormore) on the guard-bar the height of the thickness of the upper or lockbar, which will be about o11efourth of an inch. Said lock-bar may be asWide as the cutterbar, if desirable. The buttons or keepers, when madefor the above improvement, may be made With a step in the button orkeepers to suit the thickness of the upper or lock bar.

Having thus fully described my invention, What I claim as new, anddesire to secure by Letters Patent, is-

The combination, with the cutter-bar provided with studs extending atright angles thereto a distance greater than the thickness of thecutters, two studsA for each cutter, of the cutters provided with twoholes, each adapted to be slid over the studs, and the herein-describedlocking-bar provided with a series of holes corresponding to the holesin the cutters and to the studs projecting through the cutters, andfastening-screws for securing the locking-bar to the cutter-bar inengagement lwith the cutters, substantially as set forth.

In testimony whereof I aiiix my signature in presence of two witnesses.

CALEB HANK.
